To all whom t may concern:

Beit known that I', FRANK E. BOEHNCKE, a citizen; of the United' States, residing` at 58 Vanderveer Avenue, l/Voodhaven, county of Queens, and State of New Yorlnfhave invented certain new and usefulv improvements in Window Screens, of which' the follo'wingl is the specification.

This invention relates to window screens and has for its object therprovision of simple and serviceable means for screening an en"- tire window opening and at the same time permitting easy manipulation for'permitting access tobe had-to blinds, awnings, shutters, clothes-lines.I or the like, associated withl the window.

Another object is to provide a window screen for the above purpose' adapted to be readily made and applied in position either inside o r outside of the window.

Ae further object is to provide al window screen adapted` to be moved in respect to the window, without it beingnecessary to'detach the screen from the window casing, sogas. to uncover substantially the entire window for cleaning orvrepair, and to permit a portion of the screen to be moved relative` to thel en'- tire screeni portion to provide anl opening through the screeny and thereby offer ready access to the window for opening and clos-v ing they same or to shutters, awnings and clothesflineswoutside of the windowy for the manipulationl thereof-.-

My invention further contemplates a window screen havinglthe' aforesaid .characterise tics and advantages which is so constructed that the components thereof may be readily cleaned so that the structurek will meet the most rigid sanitary requirements.

My invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention of which will be indicated in the appended claim.

Similar reference characters refer to similar parts throughout the several views of the drawings, and in which is shown one of the various possible embodiments of this invention.

Figure l is a plan view illustrating the screen mounted on a window casing inside of the window, the screen being in completely closed position.

Figure 2 isy a fragmentary cross-sectional' view onthelineQ-Q of Fig. l.

Fig-ure 3 is a fragmentary detail' inper-l spective of the two smaller swinging screen portions, and

Figure l shows ini crosssection the' free' edgesof the smaller movable screen'portions when in closed position. p

Referring to the drawings,-y they window screencomprises a rigid rectangular framel l adapted to snugly fit the'interior olf-lawine' dow casing 2 and tobehinged thereto at one side by means of hinges 3v whereby Vthis frame may be swung away from the'window. A latchv 4" may be provided as' at 5, whereby framel may be locked in' closed position. Frame 1i may be .supplied with a suitable handle G or the' like to ,aid` a Vperson in) the' opening. andI closing of thescre'en as a' whole'.- Screen frame l carries al rigidv transverse frame member 7 so placed' with' respect to the top andbottomofthe screen frame that whenV the screenis in closed position' inside of a window, the window may be' readilyopened and closed from below this transe' verse member. The transverse member di'- vides-frame member ly into two'portions, the upper portion being permanently screened by any suitable' foraminous` screening mia-Y terialf, such as mosquito netting or' the; like', but the' lower portion is' provided witlta pair ofv secondary screen frames 8Y and 9, frame 8 being hinged toone vertical member of framefl, as. by hingeslO, andframe` mem ber 9* being' hinged" tothe other vertical member of frame 1,*as'by l'iinges'fll. Frame Cil members-8 and' 9fare individual screenslof any suitable material, and are' adapted, when' in closed position, to completely cover the lower portion of the main screen and that portion below transverse member 7. Members 8 and 9 may be independently movable on frame member l and should preferably always be movable interiorly of the window with which they are associated so as to permit, when open or partially open, free and ready access to awnings, shutters, clotheslines or the like. The lower edge of the transverse frame member 7 is preferably rabbetted to register with the complemental upper edges of the frame members 8 and 9 as shown at 12. The abutting edges of said frame members 8 and 9 are likewise rabbetted so that when the said frame members are in closed position a seam or joint is formed between said frame members 8 and 9 and between said members and the transverse member 7 through which an insect may not enter, the frame members 8 and 9 being held in closed position by means of a latch 13 which may be positioned onthe transverse member 7 as herein shown. The lower edges of the frame members 8 and 9 and the upper edge of the bottom frame member 7b are preferably plain surfaces, in order to eliminate the possibility of the accumulation of dust and dirt which would find ready lodgment upon the upper edge of said frame -member 7b were it provided with a rabbetted or similar surface. F urthermore by providing. the latter member with a plain surface it may be readily cleaned. Thus it will be seen that by this construction a structure is provided which.` will meet all sanitary requirements. Tolimit movement of the screen portions 8 and 9 relative to the main screen member 7b and to maintain the said movable screen portions 8 and 9 in functioning position, l provide a stop 14 which is fixed to said member 7b against which the frame member 8 abuts when the screen portions 8l and 9 are in closed position. Weather strips 15 may be applied to the window casing in the usual way to limit movement of main screen portion 1 inward of the casing and to prevent insects or the like from passing between screen frame 1 and the window casing.,

ln F ig. 2 are shown lower window sash 16 and upper window sash 17 in lowered position. Y y

It is obvious thata screen constructed in the above-manner and for the aforesaid purposes may be mounted either inside or out-VV side of the window. vWhen mounted on the inside of the window, transverse member 7 Y shouldbe highenough in the frame to permit: ofthe free and easy manipulation of the windowV `from below that member when frame members 8 and 9 are open.l When the swung .inwardly and below the window a sashes when both are inraised position and screen to be swung away from the window should be Y positioned and thereby give unobstructed passage through the window, and when the frame is positioned inside of the window to permit free access to the window for washing or to the casing for the repair or` adjustment of the window ropes, and :movement of one or both of screen members 8 and.9 inwardly permits of ready access to shutters, awnings, clothes-lines and the'like on thev outside of the window for their manipulation.

Thus it is'seen that an inexpensive, convenient and'serviceable window screen has been provided and one which accomplishes the desired objects above mentioned; 1

' Having thus fully described my invention what l claim as new and desire toV secure 'by Letters Patent is:

The combination with a window frame Vof a screenv comprising a main framecoexten sive with the opening in the window frame and pivotally ,a connected to said window frame, said mainframe'having side members and top andbottomrmembera'a trans-V verse member fastened to the side members intermediate the top and bottom members thereby providing two openings, screening permanently vcovering one of said openings, anda pair of secondary frames each having Yside members and top and bottom members, a side member of each ofthe secondary frames being hinged to a side member of theV mainA frame, the ysecondary frames, when swung inwardly, closing the lower opening in the mam frame, that portion of the transverse` frame member which cooperatesl with Y the members ofthe secondary frames and Vthe cooperating portions of the secondary frames being rabbeted, the portions of the bottom and side members of the'mainY frame and of lthe secondary frames which cooper-V' ate being smooth.
